Which larvicide is registered for use in Michigan?

Temephos is a larvicide that is registered for use in Michigan, primarily used for controlling mosquito larvae in standing water. It is effective because it acts on the developing stages of mosquitoes, preventing them from maturing into adults. Temephos targets specific enzymes that are present in the larvae, making it an effective tool for mosquito management without harming adult mosquitoes or other non-target organisms significantly.

In contrast, other options such as Sumithrin and Malathion are primarily used as adulticides to control adult mosquito populations, which makes them unsuitable for larvicidal purposes. DDT is widely known for its historical usage in pest control but has been banned or restricted in many places, including Michigan, due to environmental and health concerns. This underscores why Temephos stands out as the appropriate choice for larviciding efforts in the state.
